Embodiment approach

[0051] Antistatic agent: external coating antistatic agent of Weihai Yunqing Chemical;

[0052] Substrate: Toray's 50μm and 100μm PET substrates;

[0053] Glitter powder: Pearlescent powder from Hongtai Pigment Store in Houjie, Dongguan City.

[0054] The antistatic agent was coated on the B substrate 21 by an anilox roller, and baked at 80°C for 60s to obtain the antistatic layer 22 . Wherein the thickness of the antistatic layer 22 is 2 μm, and the thickness of the B substrate 21 is 100 μm;

[0055] Apply the UV resin on the surface of the antistatic layer 22 through a micro-gravure roller, dry at 100°C for 60s, and then cure with a UV lamp with an energy of 500mJ / cm2 to obtain the UV hardened layer. Wherein the thickness of the UV curable layer 24 is 5±1 μm;

[0056] Add 5 / 10,000 flash powder to the silicone pressure-sensitive adhesive, filter it through a 25μm filter element and a 5μm filter element, and then apply the glue on the other side of the B substrate 21 with a...

Abstract

The invention discloses a protection film with the glittering and antistatic effects and a preparation method thereof. The protection film brings a stronger aesthetic feeling. The protection film comprises a protection film layer, a use layer and a release layer from top to bottom. The use layer comprises a UV hardened layer, an antistatic layer, a B base material and a B adhesive layer. The UV hardened layer is made of UV type acrylic resin glue, and the thickness of the UV hardened layer is 2-10 micrometers. The thickness of the antistatic layer is 1-10 micrometers. The B base material is one of a PET film, a PEN film, a PE film and a BOPET film, and the thickness of the B base material is 20-200 micrometers. The main component of the B adhesive layer is an organosilicone pressure-sensitive adhesive layer, and the thickness of the B adhesive layer is 20-100 micrometers. The surface resistance of the protection film can reach 108-1010 ohm.m, and thus the good antistatic effect is achieved; the UV hardened layer can achieve the wear-resisting and scratch-preventing effects and also can prevent loss of an antistatic agent, and thus the service life of the antistatic agent is prolonged.

Description

technical field [0001] The invention relates to an optical protective film, in particular to a protective film with flash diamond and antistatic effects, and belongs to the field of protective films. Background technique [0002] Touch screens can be seen everywhere in people's daily life, and more and more touch screen protective films are appearing around us. With the development of mobile terminal equipment, people are gradually processing more and more work on smart devices such as mobile phones and tablet computers. As consumers have higher and higher requirements for screen protectors, they also hope that they can be attached Other functions can not affect the appearance. [0003] The common PET screen protective film has the advantages of high strength, good wear resistance and low cost, but its resistivity is as high as 10 12 ~10 14 Ω m, so it is easy to generate static electricity. At present, there are two main methods for antistatic modification of PET, the fi...
